Standards
This test method covers the determination of diameter, wall thickness, and length dimensions of thermoplastic pipe. Included are procedures for measurement of the inside diameter of pipe intended to be joined by internal fittings, measurement of the average outside diameter for roundtable pipe where out-of-roundness is not of primary concern, out-of-roundness measurement and measurement of the average outside diameter of non-roundtable pipe, and for determining length and straightness.
This test method covers the determination of the impact resistance of thermoplastic pipe and fittings under specified conditions of impact by means of a tup (falling weight) . Three interchangeable striking noses are used on the tup, differing in geometrical configuration. Two specimen holders are described.
The purpose of these abbreviations is to provide uniform contractions of terms relating to plastics. Abbreviated terminology has evolved through widespread common usage. This compilation of abbreviated nomenclature has been prepared to avoid the occurrence of ore than one abbreviation for a given plastics term, and double meanings for particular abbreviations.
This specification covers poly(vinyl chloride) (PVC) pipe made in standard thermoplastic pipe dimension ratios and pressure rated for water (see appendix). Included are criteria for classifying PVC plastic pipe materials and PVC plastic pipe, a system of nomenclature for PVC plastic pipe, and requirements and test methods for materials, workmanship, dimensions, sustained pressure, burst pressure, flattening, and extrusion quality. Methods of marking are also given.
This International Standard gives specifications for the angular coordinate system to be used in the design of scales, reticles or other display means incorporated in instruments for determining optical data on human eyes or corrective lenses for human eyes.
This standard establishes the basic principles for carrying out vibration measurement and processing data, with regard to evaluating vibration effects on buildings. The evaluations of the effects of building vibration are primarily directed at structural response, and include appropriate analytical methods where the frequency, duration and amplitude can be defined. It only deals with the measurement of structural vibration and excludes the measurement of airborne sound pressure and other pressure fluctuations.
This standard provides general guidance on methods of carrying out penetrant inspection
on materials and components both during manufacture and in service. It does not
deal with acceptance or rejection. Penetrant inspection is used to locate
discontinuities, such as laps, folds, cracks, porosity and fissures, which are
open to the surface of a material or component. Penetrant techniques can be
used on materials irrespective of their physical properties, provided that the surface
is normally non-absorbent and compatible with the penetrant process.
This standard provides general guidance on the verification procedures to be applied when
carrying out penetrant inspection, in accordance with ISO 3452. These tests are intended to ensure that the
penetrant system is functioning correctly and that there has been no harmful
deterioration of the process materials during service. Generally, the frequency
of checking penetrant materials and black light sources will depend on the
frequency and conditions of usage. Specific and maximum intervals should be recommended
by the manufacturer.
